Re: [Haskell-cafe] Iteratee, ghc 6.12/7.0 strange behaviour -epollControl: permission denied (Operation not permitted)

Could you please file a bug at http://hackage.haskell.org/trac/ghc/ Give an as small reproducible test case as possible and as much information about your system as possible. Thanks! Johan 2011/3/29 Michael A Baikov :

I tried with both 7.0.2 and 7.0.3

I am still playing with lastest iteratee and i think i found something strange.

let's suppose we have a file test.hs like this:

import Data.Iteratee import Data.Iteratee.IO import Data.Iteratee.Char

main = fileDriver printLines "/etc/passwd"

It works fine when executed via runhaskell / ghci in ghc 6.12. Compiled version in ghc 7 also works, but when i am trying to execute it via runhaskell / ghci i am getting this error:

iter.hs: epollControl: permission denied (Operation not permitted)

Any ideas?

Make sure you have at least GHC 7.0.2. There were some I/O manager bugs in 7.0.1.
